MORIsON, Whelan Patent, No. 358,584-while the slotof Chicago, in the State of Illinois, and irons have been placed on top of ties and the CHARLES VOGEL, of San Anselmo, in the State cable has run above the ties, the side pieces 5 of California,hav'e invented certain new and were not connected together and a concrete 5 5 useful Improvements in Conduits for Cable or other drain has been provided under the or Electric Tramways, of which the following ties to carry off the drainage.

For exam- 50 In such cable roads as have been constructed ple, in Fig. 2 it is shown as iiat, whereas in roo Figs. 3 and 4 it is given a downward curve, which may be useful in facilitating the drainage of the conduit. To the bottom iron of the conduit is secured a cross-piece of angleiron 14 15, the forni of which may be made to correspond with the bottom iron, as shown. respectively, in Figs. 2, 3, and 4. To each side iron is bolted a vertical piece of angle-iron 16 E7. The diagonal plate 18 is secured at one end to the projecting flange 17 and at the other end to the projecting 'flange 15 on one side of the conduit, and the diagonal plate 19 is secured to the corresponding flanges on the other side of the conduit. When the structure is thus Completed, it is vonly necessary in laying it to fasten the side and bottom pieces to each cross-tie, as by the lagscrews 2O and 2l, and we thus have a structure thoroughly braced and strong, which may be completed before being laid and which is self-sustaining independent of the cross-ties.

Ve will now describe the construction of the pulley-pockets. One of the slot-irons and its connected side iron and flange are stopped oft'at the lines z .e and w w, Fig. G. A pocket 22 is cast, having a drainage-opening 23 at the bottom and the flange 24 extending around its upper edge. This flange is secured to the under side of the adjacent ends of the bottom plate l2, and also to the under side of the flangev 11 between the ends of the bottom plate, the flange 24 being thickened at that point to an extent corresponding with the thickness of the bottom plate, as shown in detail in Figs. 8 and 9. 25 is a bridge-piece, of cast-iron,de signed to bridge the opening at the side of the pul ley, provided with flanges 26 and 27, by which it is secured to the extremities of the side irons 8, and with a liange 28, which is secured to the top of the flange 24. This flange 2S is rabbeted at 29, so as to overlap the flange 10 of the side irons S, and the rabbeted portion of the flange 29 is in one piece wl'ithgthe flange 2G, as shown in dotted lines in 11g. beted all around, as at 30, to provide for the support of the cover 3l, the flange 32 of which fits snugly into this rabbet. An overhanging lip 33 is provided on the bridge-piece 25 at the rear of the cover to hold the cover down at that part and to preventits being removed, except as it is raised at the front edge, as indicated in Fig. 7. Between the adjacent ends of the side irons 6 a nose 34 projects from the cover 3l, so as to exactly fill out the space above the pulley left vacant by stopping off the slot-iron. Thus the nose 34 of the cover when in position performs the function of the slot-iron, the whole operating as though the slot-iron were continuous; but when the cover is removed it exposes substantially the whole interior of the pulley-pocket and gives ready access to the pulley from above for any purpose required, thus enabling a much smaller pulley-pocket to be employed than was necessary in the old form of construction.

W'ithin the p iilley-pocket 22 are cast four The top of the bridge-piece 25 is rablugs 35, 36, 37, and 38, which serve to support four corners Of the frame 39, upon which are mounted the bearings ot' thelpulley 40. We prefer t0 make the following provision for these bearings at each end of the pulley: Two parallel arms 4l 42 project upward from the frame 39 and are pierced by the inversely-operating set-screws 43 44. Between the points of these set-screws is suspended the journalbox 45, provided with the oiler 46. This method of mounting the bearings enables them to be adjusted with great accuracy, and the location of the bearings upon the frame 39, separate from the casting 22, enables the pulley, practically, to be mounted before it is placed in position in its pocket.

In practice the pulley-pockets will be placed alternately on opposite sides of the conduit, as shown in Fig. 10. This arrangement is easily made with the construction of conduit described, because by making all the side irons 0f equal length and placing them together, so that they overlap each other at opposite ends by one-half the length of a pulleypocket, and so that the two overlapping ends abut against each other, the sections of the conduit between every two pulley-pockets will be duplicates of each other, only with a reversed arrangement.

In our description we have shown in connection with the conduit the pulleys adapted for a cable tramway; but the necessary apparatusfor employing the conduit in connection with an electric railway will be well known to persons skilled in the art without description or illustration.

We claimf 1. A railway-conduit constructed in sections, the side pieces of each section overlapping each other at opposite ends of the sections, whereby when the sections are placed together endto end openings will be left alternately on opposite sides for the pockets, substantially as described.

2. In combination with a railway-conduit having a section removed from its bottom plate and one of its side plates7 a pocket bridging the opening beneath and secured to the adjacent ends of said bottom plate, and an inclosure bridging said opening at the side and secured to the adjacent ends of said interrupted side plate and also to said pocket, substantially as described. Y

3.' In combination with the rails and crossties, a conduit resting on top of the cross-ties, having its two side pieces secured together independently of the cross-ties, and a series of pulley-pockets attached to the side and bottom of the conduit between the cross-ties, substantially as described.

4. In combination, the bottom plate, the two side plates, one of which is interrupted adjacent to the pulley, the pulley, and an inclosure for said pulley and said opening in the side plate so constructed and arranged that a mantio hole is provided extending and giving access to the cable and the pulley all the way from ley and said opening in the side plate, and

an underneath support for the bearing of said pulley, the Whole being so constructed and arranged that the said pulley may be lifted from said support upward and laterally into the man-hole provided by said inelosure through the opening provided by the interruption of said side plate, substantially as described.
